Hyperglycemia, or high blood glucose, occurs when there is too
much sugar in the blood.
Causes of hyperglycemia

- Eating the wrong foods
- Eating too much food
- Infection
- Illness
- Increased stress
- Decreased activity

It is important to know the early signs of hyperglycemia. If hyperglycemia
is left untreated, it may develop into an emergency condition called
ketoacidosis.
Signs and symptoms of hyperglycemia include:
- Increased thirst
- Blurred vision
- Frequent urination
- Increased hunger
- Numbness or tingling in the feet
Additional early symptoms include:
- Fatigue (feeling weak, tired)
- Sugar in the urine
- Weight loss
- Blood glucose of more than 180 mg/dl
- Vaginal and skin infections
- Slow-healing cuts and sores
How to treat and prevent hyperglycemia
If you have any of the early signs and symptoms of hyperglycemia you need
to:
- Test your blood glucose.
- If you have type 1 diabetes and your blood glucose is more than 300
mg/dl, test your urine for ketones.
- Call your doctor if your blood glucose is greater than 180 mg/dl for
more than one week or if you have two consecutive readings greater than 300
mg/dl.
- Drink non-caffeinated and non-alcoholic beverages that do not contain
sugar.
- Make sure you are following your meal plan, exercise program, and
medication routine.
When you have hyperglycemia for long periods of time, damage to
nerves, blood vessels, and other body organs can occur.
